Hookes Law SC1

Do Elastic bands follow Hookes Law?

Aim: To investigate elastic bands, whether they follow Hookes Law.

Equipment: Stand, boss, G Clamp, Elastic band, ruler, weights

Diagram:

image00.png

Method:

  • I will setup my equipment as I have shown in my diagram.
  • I am going to do 3 experiments using different elastic bands. In the 1st experiment I will add masses in small amounts.
  • On the 2nd experiment, I will keep loading weights until near breaking point.

Middle

  • Once I have all my results I will then take the weights off 1 by 1 to see if the elastic band returns to its original form. I will only do this for the 1st and 2nd experiment.

Safety:  

  • I will have to wear goggles so when the elastic band snaps it won’t flick in my eye.
  • I will use a G Clamp so the equipment won’t fall.
  • I won’t put my feet under the table as the weights might fall.

Fair Test:

I will make this a fair test by:

  • I will make the results accurate.
  • I will use the same equipment.
  • I will keep the ruler at the same height

Prediction:

First Experiment:

Conclusion

Evaluation:

My results were reliable, but to get my results more accurate I would like to repeat the experiment, my rules was moving too much, so I think I could have had another person to hold the ruler, this would prevent the ruler from moving about, and would make my results more accurate.

I did get some unusual results on my graphs, but I am not sure what caused them, I feel it was to do with my inaccurate results. For improvements I would repeat the experiment, and I would take more time over it, especially when I measured with a ruler. I feel overall I have had really good results but for the best results I would need more time so I could get more accurate results.

Here's what a teacher thought of this essay

3 star(s)

Overall a 3 star piece of work. The practical procedure should yield some valid data. It is a method that could be followed by other people. The conclusion could be improved and expanded on. There needs to be some explanation of the results achieved. Why did this happen when this was done? Link it in to the science.

    The only thing that was hard to keep constant, and was not maintained in this experiment was the thickness of the vessels, which was only an approximate. Because of this, there was no replication for the experiments, as each cutting of blood vessel had a different cross-sectional area, causing variation in results.
